摘要
机动飞行条件下的航空发动机转子振动特性研究是近年来的研究热点,但在实际工程中该课题的研究尚不多见。从航空发动机转子一般模型出发,提出了机动飞行条件下发动机转子振动特性的一般性,并利用某型发动机的试飞数据进行了验证和分析。结果表明,实际飞行分析结果与提出的观点相吻合。
Recently, research on aero-engine rotor vibration characteristics is becoming a hot spot, but the studyin engineering is still at the beginning and more work need to do further. Generic model of aero-engine rotor is analyzed and proposed a generic idea of aero-engine rotor vibration characteristics in pitching maneuvers, then the data of an engine in flight test are analyzed, and the verification is done. The resuhs show that the verification of real flight test accord well with the idea.
